Description of key information
Additional information
Aquatic/sediment:
In accordance with column 2 of Annex IX, the study does not need to be conducted if the substance has a low potential for bioaccumulation. The log Kow of 1.1 for butyric acid (OXEA, 2009) indicates a low potential for bioaccumulation. In addition the substance is readily biodegradable (Hüls, 1996). Therefore and for reasons of animal welfare a fish study is not performed.
The log BCF of butyric acidwas estimated to be 0.5 (BCF = 3.162) using the program BCFBAF v3.00 (Part of US EPA EPI Suite v4.00). In addition, a log BAF (upper trophic) of 0.31(BAF = 2.06) was calculated using the method of Arnot-Gobas(ECT, 2010). The low BCF/BAF values indicate a low potential of butyric acid for bioaccumulation in aquatic organisms.
Terrestrial:
